Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve fluid
pressure. Have a container ready to catch the
drainage.

4. Align the new air valve gasket (105*) on the
center housing, then attach the new air valve.

3. Pull the cup (213) off of the base (212). Remove
the o-ring (214) from the cup.
4. Remove the retaining ring (210) from each end
of the air valve. Use the piston (202) to push
the end cap (207) out of one end. Remove the

8. Remove the pilot valve cartridges only if
necessary due to a known or suspected problem.
After removing pilot valves, use a hex to remove
